Scenes for the upcoming Netflix series "The OA" were being filmed Tuesday at Survival Systems USA in Groton, ending a two-day shoot there.

The drama stars Brit Marling who co-created and co-wrote it with director Zal Batmanglij. They had worked together previously on the feature films "The East" and "The Sound of My Voice."

"The OA" focuses on a blind young woman who disappears for seven years — and returns being able to see.

Asked Tuesday what scenes were being shot at Survival Systems, producer Jill Footlick said, "I'm not sure I can tell you that. There's not a lot I can tell you, to be honest."

That's part of the fun, she said, maintaining the mystery of the story until the public gets to see it.

She did say, though, that the scenes feature a crash and the actors and stunt people were in the water at Survival Systems, which offers training in underwater and surface water survival as part of its business. Survival Systems is located across the street from Groton-New London Airport.

Cynthia Arntzen of Netflix Original Series Publicity could not be reached for comment.

These were the only days that "The OA" was filming locally, where about 120 people worked on set. The rest is being shot in New York.

There isn't a release date yet for the eight one-hour episodes of "The OA."
